Liberal internationalism is a foreign policy doctrine that argues two main points: first, that international organizations should achieve multilateral agreements between states that uphold rules-based norms and promote liberal democracy, and, second, that liberal international organizations can intervene in other states in order to pursue liberal objectives. The latter can include humanitarian aid and military intervention. This view is contrasted to isolationist, realist, or non-interventionist foreign policy doctrines; these critics characterize it as liberal interventionism. History Liberal internationalism emerged during the nineteenth century. Prominent thinkers included Lionel Curtis, Alfred Zimmern and Norman Angell. Among policymakers, liberal internationalism influenced British Foreign Secretary and Prime Minister Lord Palmerston, and was developed in the second decade of the 20th century under U.S. President Woodrow Wilson. In this form it became known as Wilsonianism. After World War I apparently manifested among the intellectual founders of the League of Nations and also from various overlapping ideas such as classical radicalism, as well as political parties communions such as International Entente of Radical and Similar Democratic Parties. Daniel Deudney and John Ikenberry have also associated liberal internationalism with foreign policy ideas promoted by Franklin D. Roosevelt. Paul K. MacDonald has linked diplomatic practices developed at the 1899 and 1907 Hague conferences as being key repertoires of subsequent liberal internationalism. Theory The goal of liberal internationalism is to achieve global structures within the international system that are inclined towards promoting a liberal world order. It foresees a gradual transformation of world politics from anarchy to common institutions and the rule of law. To that extent, global free trade, liberal economics and liberal political systems are all encouraged. In addition, liberal internationalists are dedicated towards encouraging democracy to emerge globally. Once realized, it will result in a 'peace dividend', as liberal states have relations that are characterized by non-violence, and that relations between democracies are characterized by the democratic peace theory. Liberal internationalism states that, through multilateral organizations such as the United Nations, it is possible to avoid the worst excesses of "power politics" in relations between nations. In addition, liberal internationalists believe that the best way to spread democracy is to treat all states equally and cooperatively, whether they are initially democratic or not. According to Abrahamsen, liberal internationalism provides more opportunities to middle powers to advance their economic, security, and political interests. Examples Examples of liberal internationalists include former British Prime Minister Tony Blair, U.S. President
